I came across an interesting article today that talks about various things that people get wrong when estimating the risks. Some of them I knew, some not, but what impressed me was this curious bit:
If the risks of smoking marijuana are coldly compared to those of playing high-school football, parents should be less concerned about pot smoking. Death by marijuana overdose has never been reported, while 13 teen players died of football-related injuries in 2006 alone. And marijuana impairs driving far less than the number one drug used by teens: alcohol. Alcohol and tobacco are also more likely to beget addiction, give rise to cancer, and lead to harder drug use.
Makes one wonder indeed…
